475944 divided by 30 
The aim is to understand the frequency of 30 in 475944.

Moving on to step 1:
If we divide 4 by 30, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 30

On to step 2:
30 can be fit into 47 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 30 from 47 leaves us with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 30

Going ahead to step 3:
175 divided by 30 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 150 from 175 leaves us with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 30

Let's proceed to step 4:
If we divide 259 by 30, we get 8 and a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 158.0
If we take 240 away from 259, we end up with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 30

Let's proceed to step 5:
When dividing 194 by 30, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 1586.0
Subtracting 180 from 194 leaves us with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 30

Going ahead to step 6:
30 goes into 144 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 15864.0
Subtracting 120 from 144 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
240 divided by 30 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 15864.8
If we take 240 away from 240, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15864.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15864.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 15864.8 with a remaining 0.0.
